  drm/i915: duplicate desired mode for use by fbcon.
  drm/via: vfree() no need checking before calling it
  drm: Replace DRM_DEBUG with DRM_DEBUG_DRIVER in i915 driver
  drm: Replace DRM_DEBUG with DRM_DEBUG_MODE in drm_mode
  drm/i915: Replace DRM_DEBUG with DRM_DEBUG_KMS in intel_sdvo
  drm/i915: replace DRM_DEBUG with DRM_DEBUG_KMS in intel_lvds
  drm: add separate drm debugging levels
  radeon: remove _DRM_DRIVER from the preadded sarea map
  drm: don't associate _DRM_DRIVER maps with a master
  drm: simplify kcalloc() call to kzalloc().
  intelfb: fix spelling of "CLOCK"
  drm: fix LOCK_TEST_WITH_RETURN macro
  drm/i915: Hook connector to encoder during load detection (fixes tv/vga detect)
